Answer:
commutative property
Step-by-step explanation:
You switched the numbers inside the parenthesis, which in this case is 5 and -5.
Note what i actually represents.
i is the very basis of a whole new level of counting. When finding discriminants, we often say that a quadratic has no
real roots if the discriminant is 0. Needless to say, there are roots, they are just imaginary.

, in real terms, is non-existent. That is, there are no numbers in the real number system that when multiplied by itself produces a result of -1. This is what i unit represents.
Let's tackle this problem in smaller steps.
Let's first expand our brackets.
(i - 7i)² = (-6i)² = 36i²
Now, let's distribute the xi.
xi(i - 7i)² = xi(36i²) = 36xi³ =

= -36xi
Answer:(x+3) 2−7
Step-by-step explanation:
For this case we have the following polynomial:
5x2 - 3x - 14
What we must do is factorize to find the dimensions of the rectangle.
We have then factoring:
(5x + 7) * (x-2)
Answer:
the possible dimensions of the carpet are:
(5x + 7)
(x-2)
